Constrained Spline Smoothing [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2008
Several results on constrained spline smoothing are obtained. In particular, we establish a general result, showing how one can constructively smooth any monotone or convex piecewise polynomial function (ppf) (or any $q$-monotone ppf, $q\geq 3$, with one additional degree of smoothness) to be of minimal defect while keeping it close to the original ...

Five-Axis Tool Path Smoothing based on Cubic B-Spline Curves [PDF]

open access: yes한국정밀공학회지, 2020
In CNC machining, NC data created by CAM software is usually linearly interpolated. This linearly interpolated tool path, however, may degrade the dynamic motion performance of the machine tool and the geometric accuracy in comparison with the reference ...

Regression with Ordered Predictors via Ordinal Smoothing Splines

open access: yesFrontiers in Applied Mathematics and Statistics, 2017
Many applied studies collect one or more ordered categorical predictors, which do not fit neatly within classic regression frameworks. In most cases, ordinal predictors are treated as either nominal (unordered) variables or metric (continuous) variables ...

Smoothing variational splines

open access: yesApplied Mathematics Letters, 2000
The authors define a smoothing variational spline function by minimizing a quadratic functional in a Sobolev space and prove the convergence of the constructed splines.

Principle of Duality in Cubic Smoothing Spline

open access: yesMathematics, 2020
Fitting a cubic smoothing spline is a typical smoothing method. This paper reveals a principle of duality in the penalized least squares regressions relating to the method.

Combination Estimation of Smoothing Spline and Fourier Series in Nonparametric Regression

open access: yesJournal of Mathematics, 2020
So far, most of the researchers developed one type of estimator in nonparametric regression. But in reality, in daily life, data with mixed patterns were often encountered, especially data patterns which partly changed at certain subintervals, and some ...

Doppler‐aided Global Navigation Satellite System position estimation with B‐spline smoothing strategy

open access: yesIET Radar, Sonar & Navigation, 2022
Smoothing process can effectively improve the accuracy of the Global Navigation Satellite System (GNSS) position estimation algorithm. In this study, a Doppler‐aided GNSS position estimation algorithm with a B‐spline smoothing strategy is proposed.

A Spline Smoothing Newton Method for Semi-Infinite Minimax Problems

open access: yesJournal of Applied Mathematics, 2014
Based on discretization methods for solving semi-infinite programming problems, this paper presents a spline smoothing Newton method for semi-infinite minimax problems. The spline smoothing technique uses a smooth cubic spline instead of max function and
